IMPROVEMENT IN WINDNIILLS.

Specification forming part of Letters Patent No. 179,333, dated June 27,1876; application led May 13, 1876.

To all whom it may concern:

Be it known that I, CHRISTIAN H. MILLER, of Northville, in the county ofLa Salle and in the State of Illinois, have invented certain new anduseful Improvements in Windmills; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in certain improvements onwindmills, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and.

use the same, I will now proceed to describe its construction andoperation, referring to the annexed drawing, in which- Figure l is aperspective view of the windmill, and Fig. 2 is a detailed section of apart thereof.

A represents the main frame pivoted horizontally on the pipe'B, which isto be secured to a mast or tower in any convenient manner. D and E arethe hinges of the rudder F, which loosely embrace the pipe, one at thetop and the other at the bottom ofthe main frame, thus pivoting therudder horizontally for the purpose of directing the mill, and thehinges having their pivotal point on the same vertical line as thepivotal point of the mill. The upper portion of the main frame A, formstwo uprights. In the front uprightis the shaft K, upon which thewind-wheel is secured. Upon the rear upright of the main frame isrigidly secured the side vane G, on a horizontal line with the center ofthe wind-wheel, and in rear of and extending on both sides of thepivotal point of the mill. This side vane has at its end nearest theframe, a rod, H, the upper end of which is pivoted to the vane so as toturn in any direction, and its lower end is pivoted in the same mannerto a rod, I, near the center thereof. The upper end of the rod I ispivoted in a like manner to the rudder F, and has at its lower end theweight J. A heavy wind pressing against the side vane tends to swing it,and the wind-wheel around parallel with the rudder, and the weight, bythe operation of the rods, tends to return it to its natural position.The weight is intended to be moved along the rod I, to vary thesensitiveness of the mill to the wind.

To stop the mill, the cord L is provided, as shown, by which theoperator on the ground can bring the side of the rudder parallel withthe side of the wind-wheel.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is-

l. The side vane G, rigidly secured to the frame on a horizontal linewith the center of the wind-wheel, when the said side vane shall be inrear of and extend onlboth sides of the pivotal point of the mill,substantially as herein set forth.l

2. The combination of the rudder F, provided with hinges D E, the hollowpost B, provided with a shoulder on which rests the hinge E, andthepframe A, provided with a shoulder upon which rests the hinge D, allsubstantially as and for the purposes herein set forth.

3. The combination of the rudder F, the stationary vane-arm G, andtherod I, pivoted to the rudder, provided with the weight J, and connectedto the vane-arm by the rod H, all substantially as and for the purposeshere-in set forth.

In testimony that I claim the foregoing I have hereunto set my hand this31st day of March, 1876.
